So the greatest common factor 21,579,671 is 1.
Lets's calculate LCM of 269,538,146
2 | 269, 538, 146 |
269 | 269, 269, 73 |
1, 1, 73 |
∴ So the LCM of the given numbers is 2 x 269 x 1 x 1 x 73 = 39274
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39274
Therefore, the GCF of Fractions 21/269,579/538,671/146 is 1/39274
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 269,538,146 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(269,538,146) = 1
common factors(in case of two or more numbers have common factors) = 538
GCF(269,538,146) x common factors =1 x 538 = 538
LCM(269,538,146) = ( 269 × 538 × 146 ) / 538
LCM(269,538,146) = 21129412 / 538
LCM(269,538,146) = 39274
